Mold heating tubes are seamless metal tubes used in various heating equipment. Seamless metal pipes mainly include titanium pipes, stainless steel pipes, carbon steel pipes and copper tubes. The heating tube has simple structure, high efficiency and strong adaptability. Let's talk about the reasons why the heating tube is broken.
1. In the powder filling process, magnesium powder is mixed with impurities, carbonized at high temperature, long-term use will lead to pipeline rupture;
2. The choice of materials is very important. There are many types of stainless steel. We must choose the right material according to the environment in which the heating tube is used. In addition, the pipeline itself is different. If there is no welding, the pipe will break. Usually, this kind of problem does not usually occur in seamless pipelines. So this can also be caused by the quality of the seam pipe;
3. The liquid used by stainless steel electric heating tube for heating is also different. Some are corrosive liquids, some are water. The heating rate may also be related to water quality. Many may be groundwater or tap water, so there are many impurities, and it is easy to form fouling and scaling. Too thick will cause the internal temperature to not disperse, which will then cause the heating tube to burst.
4. The wall of the heating tube is too thin, or the power of the heating tube is set too high, the surface load is too large, and the internal temperature is too high, which will only lead to the expansion of the heating tube, which in turn leads to the rupture of the heating tube.
